【摘要】 目的 对地榆配方颗粒进行质量标准研究。方法 采用薄层色谱法对地榆配方颗粒进行定性鉴别，采用高效液相色谱法对地榆配方颗粒中没食子酸进行含量测定。结果 定性鉴别薄层色谱特征明显，专属性强；高效液相色谱法能进行没食子酸的含量测定。该方法的线性范围为0.776～3.88μg(r=0.9998)，平均回收率为100.3%(RSD=1.2%，n=5)。结论 本法操作简便、准确，重复性好，能有效控制地榆配方颗粒的质量。

    【Abstract】 Objective To study the quality standard for Diyu despensing granules.Methods Diyu despensing granules was identified by TLC，gallic acid could be determined by HPLC.Results The quality control study showed that the characteristic for identification by TLC was distinct and hightly specific， gallic acid in Diyu despensing granules was determined. The linear relationship of gallic acid was at the range of 0.776～3.88μg(r= 0.9998).The average recovery was 100.3%(RSD=1.2 % ...... 濡傛灉鎮ㄥ湪浣跨敤鎵嬫満绛夋祦瑙堟椂鏃犳硶鏌ョ湅鎴栦笅杞藉叏鏂囷紝鍙兘鏄鎼滅储寮曟搸澶辩湡鈥滆浆鐮佲€濓紝璇风偣鍑诲睆骞曟渶涓嬫柟鐨勨€滅數鑴戠増鈥濇垨鈥滃師缃戦〉鈥濊闂€�
